An older gothic man who is far too old to be hanging out with teenage goth kids or dressing like an Anne Rice character, seen as a sort of father figure by the younger, more impressionable gothic teenagers. He is usually a supplier of hallucenogens and ecstacy in the hopes of bagging a child. In essence, he is a pedophile who wears theatrical makeup and ridiculous pop-in fangs.

Hey, we're all meeting at Sabbath's house tonight, you comin'? No, that guy's a total grampire, don't fall asleep over there.

A grampire is a lecherousold guy who hits on young people to befriend or score with them in order to suck their youth, to feel young themselves. Male equivalent of cougar but not as acceptable. First seen in the book Still Life With Cat and Mouse, by Sheila McGraw.

James: Look what just creaked into the bar.
Eric: Jeez, that geezer is so old I bet he's a greeter at Walmart.
James: I've seen him here before always going after the young kids. OMG he's hitting on that twinkie Terry.
Eric: He's practically a pedophile. What a grampire.
